WebApr 10, 2024 · In this context, recently it has been argued that (a) there exists a power law relation between the mass of the soliton and mass of the surrounding halo called the Soliton-Halo (SH) relation, and, (b) the requirement of satisfying observed galactic rotation curves as well as SH relations is so stringent that ULDM is disfavoured from comprising …
WebWe will demonstrate the soliton resonance in a Bose condensate. BEC of weakly interacting atoms is described by Gross-Pitaevski equation for the order parameter w(x, t ) : J where g … WebCreating stable solitons or self-trapped modes in systems with a dimension higher than one remains a challenging and attractive problem in physics, both in theory and experiments [1,2].The main obstacle lies in the ubiquitous cubic nonlinearity, which could be the Kerr effect in optics [] or the intrinsic ones induced by two-body scattering in Bose–Einstein …

It has already been established that its multisoliton interactions in the adiabatic approximation can be modeled by the Complex Toda chain (CTC). The fact that the CTC is a completely integrable system, enables us to determine …
